TypeID Go

A golang implementation of TypeIDs

TypeIDs are a modern, type-safe, globally unique identifier based on the upcoming UUIDv7 standard. They provide a ton of nice properties that make them a great choice as the primary identifiers for your data in a database, APIs, and distributed systems. Read more about TypeIDs in their spec.

This particular implementation provides a go library for generating and parsing TypeIDs.

Installation

To add this library as a dependency in your go module, run:

go get go.jetify.com/typeid

Usage

This library provides a go implementation of TypeID:

import (
  "go.jetify.com/typeid"
)

func example() {
  // Generate a new TypeID with a prefix (panics on invalid prefix)
  tid := typeid.MustGenerate("user")
  fmt.Println(tid)
  
  // Generate a new TypeID without a prefix
  tid = typeid.MustGenerate("")
  fmt.Println(tid)
  
  // Generate with error handling
  tid, err := typeid.Generate("user")
  if err != nil {
    log.Fatal(err)
  }
  
  // Parse an existing TypeID
  tid, _ = typeid.Parse("user_00041061050r3gg28a1c60t3gf")
  fmt.Println(tid)
  
  // Convert from UUID
  tid, _ = typeid.FromUUID("user", "018e5f71-6f04-7c5c-8123-456789abcdef")
  fmt.Println(tid)
}
